@murphy, danke! woher hast du das? Selbst gewußt oder gerade aus einer
Doku gelesen? wenn aus einer Doku, dann würde mich der Link interessieren...

fault/s
   Number of page faults (major + minor) made by the system per second
   (post  2.5  kernels  only). This is not a count of page faults that generate
   I/O, because some page faults can be resolved without I/O.

majflt/s
   Number of major faults the system has made per second, those which
   have required loading a memory page from disk (post 2.5 kernels only).


Das heißt mit anderen Worten, dass die Werte unter "faults" alles reine
"minor faults" sind, also allokierter Hauptspeicher für Programme. Wenn
die "majflt/s" größer Null wären, dann müsste ich "faults minus majflt/s"
rechnen, um die tatsächlichen "minor faults" herauszubkekommen?

Edit:
Wie groß ist eine Page auf gängigen Linuxsystemen? 1 Byte?\n\n
